Right now many companies use the 3G network to give internet access to their range of popular smartphones such as the Android and iPhone OS.

4G is expected to cover 95% of the UK’s mobile VoIP service and provide fast speeds, efficient service and low cost calls. It will offer a secure IP telephony solution for all mobile devices including smartphones and laptops.

The news is not so good for fixed line telecommunications companies which are fighting against the tide – last year saw one million less fixed line users. The way this trend is going the landline could be completely obsolete in two decades.

Although 4G phones will be expensive to start with they will gradually become more affordable. And even though fixed line calls may remain cheaper the convenience of mobiles makes then a preferable option for many consumers.

Expect a worldwide movement to 4G next year as even countries as far afield as Sri Lanka have discussed the possibility of a total roll out. Wherever in the world they are based the opportunities for mobile VoIP providers are endless.
